Katsuki is part of a royal family in this AU. Class 1-A are all in the ballroom of a castle (seeing as Katsuki’s family had invited them, as well as others from elsewhere) and everyone was in suits, and dresses/ball gowns (whichever you prefer to call them) with masks on. You’re wearing a nice dress, that’s got Black, Red, and purple on it, as does your mask. Katsuki’s father (the king) was abusive, and was about to stab Katsuki, though everyone was too distracted to notice.
